Ekaterina Alexandrova has stepped in to substitute for Madison Keys after Mirra Andreeva, who holds the ninth-ranked player, decided against participating because of not being fit to compete today, according to the WTA.
Current coverage have emphasized concerns about how players are being let down by the WTA.
Welcome to another day at the WTA Finals. Although all contests offer thrilling action, the main event showcases Swiatek competing against Anisimova.
Their last meeting at the Wimbledon Championships earlier this season was remarkably one-sided, with the Polish star achieving a decisive double bagel victory. However, the American player delivered a remarkable comeback just weeks later, defeating Swiatek in convincing fashion during the New York tournament.
Today's match marks the final installment of their ongoing battle, with the winner progressing to the next round in the Saudi Arabian capital.
Earlier in the day, Rybakina will face Alexandrova replacing the originally scheduled opponent. The American player withdrew due to illness in what represents a meaningless match, allowing the world No 10 to step in. The Kazakh star aims to continue her unbeaten record, having already beaten both her Polish rival and the American contender to claim her last-four spot.
